High Performance SCM Solutions
- for the cement and concrete industry.
Calcined Clay Upgrading
Using clay as a pozzolan is well known, however, due to the large variability in the raw material, the compressive strength fluctuates from batch to batch. We have developed a technique to not only reduced these performance fluctuations, but at the same time increased the compressive strength by 10-15% for low grade clays containing large parts of smectite and chlorite.
High Strength Shale SCM
We have improved the process of producing calcined shale for use as a supplementary cementitious material. By using cutting edge research and our extensive knowledge of mineralogy and clay chemistry, we have succeeded in increasing the strength of the finished calcined shale product. At the same time we have reduced the discoloration that usually occurs when calcining shale.
Treatment of Marine Sediments
Sediments containing clay minerals are abundant in harbours, river deltas and in coastal areas. These areas are usually regularly dredged in order to achieve the desired depths needed by the marine traffic. These excavated sediments are usually just dumped in another place, but can instead be dried and upgraded effectively using our clay upgrading process, resulting in a high performance SCM.
